HTTP Login Gate

Hey n8n-ers! I’m trying to automate a .csv retrieval from behind a http login gate. I’ve managed to do this previously, but this current login gate is not playing ball - can anyone help me see what i am doing wrong?

Here’s the http sniffer data of my successful (manual) retrieval:

Hi @Luke_Austin, I am not familiar with this website, so I am not sure if you’re doing anything wrong here. Perhaps you can share some additional details? What exactly isn’t working in n8n for you?

Hi @MutedJam! I wouldn’t expect you to be familiar, it’s a bike parts distributor in the UK!

I’m trying to:

  1. log in, via their portal @ www
  2. when authenticated, kick off a bit of PHP that downloads the latest data feed for their products - Chicken Cycle-Kit B2B

If i can get those two to work, i’ll be saving the file in my local file system, for further processing.

At the moment, I can’t get the second HTTP node to accept the PHPSESSID cookie retrieved by the first, so i can;t kick off the php script with my POST request.

I can DM you my username / password to access the site, if required - for testing. As long as you promise not to order a million chains for me or something…
